The Browns season was a mess and Stefanski basically gave up playcalling when Watson went down so that the stink of what followed was on Dorsey.
But when you watch them... a lot of the same issues we saw when he was here arose. Dreadful at blitz pickup, seeming lack of hot route adjustment, receivers runnning downfield and ending up crashing into one another at the same spot, total lsck of quick game. Limited motion even as a means of identifying coverages.
Just all a mess. I don't think he is good at this. If he wants to coordinate college is his route. If he wants to coach in the NFL I am sure there will be QB coach opportunities for him.
